Inspection and Verification

Visually inspect for obvious signs of mechanical or electrical damage.

VISUAL INSPECTION CHART

Mechanical	Electrical
Accessory drive belt Brake fluid level Door adjustment Engine coolant level Engine oil level Fuel evaporative system Fuel tank Tire pressure Luggage compartment lid adjustment	Smart junction box (SJB) fuse(s): 13 (7.5A) 23 (7.5A) 27 (7.5A) 28 (10A) Wiring, terminals or connectors Message center switches Key-in-ignition warning switch (part of the ignition switch) Smart junction box (SJB) Instrument cluster (IC)

If the cause is not visually evident, correct the cause (if possible) before proceeding to the next step.

NOTE: Make sure to use the latest scan tool software release.

If the cause is not visually evident, connect the scan tool to the data link connector (DLC).

NOTE: The vehicle communication module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.

If the scan tool does not communicate with the VCM:
- Check the VCM connection to the vehicle.
- Check the scan tool connection to the VCM.
- Refer to MODULE COMMUNICATIONS NETWORK article, No Power To The Scan Tool, to diagnose no communication with the scan tool.
If the scan tool does not communicate with the vehicle:
- Verify the ignition key is in the ON position.
- Verify the scan tool operation with a known good vehicle.
- Refer to MODULE COMMUNICATIONS NETWORK article to diagnose no response from the PCM.
Carry out the network test.
- If the scan tool responds with no communication for one or more modules, refer to MODULE COMMUNICATIONS NETWORK article.
- If the network test passes, retrieve and record the continuous memory DTCs for the instrument cluster (IC), the restraints control module (RCM), the SJB, and the PCM.
Clear the continuous DTCs and carry out the self-test diagnostics for the instrument cluster (IC) and the SJB.
If the DTCs retrieved are related to the concern, go to DTC Charts. For all other module DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES article.
If no DTCs related to the concern are retrieved, go to Symptom Chart - Instrument Cluster (IC) , go to Symptom Chart - Information And Message Center or Go to Symptom Chart - Warning Chimes .
